I just use the following line against v$transaction to see which transactions are rolling back  

,case when bitand(t.flag,power(2,7)) > 0 then 'RB in Progress'

                                         else 'Not Rolling Back'
                                         end as "F Status"

You can use this line with any of your queries against v$transactions without having to refer to an x$ view.
It works on all versions of Oracle from 8.0 to 9.2. I have not tested it on version 10 yet.

Thanks, but it looks like that one does the same thing as the one you referred me to yesterday
(http://www.ixora.com.au/scripts/sql/9.0/rolling_back.sql), and in fact that script looks suspiciously similar to the script on ixora. I think somebody may have done some borrowing :-)

	It appears there is a script that may do what you want.
	
	I haven't tested it for accuracy.

		This seems to be as good as it gets.
		
		I don't know if this improves in 10g.

                        Anyone know of a quick way to identify any/all transactions currently being rolled back? I know I could look for decreasing used_ublk in v$transaction, or increasing undo statistics in v$sesstat, but is there anywhere that a transaction is simply flagged as currently being rolled back, so you can quickly identify it w/o having to check for deltas?
